LUBRICATOR. l

SPECIFICATION forming part of Letters Patent No. 275,971, dated April 1'7, 1883.

Application filed October Q7, 1882. (No model.)

To all whom it may concern:

Be it known that I, HIRAM ALLToN, a citizen of the United States, residing at Wilmington, in the county of New Castle and State of Delaware, have invented certain new and useful Improvements in Lubricators; and I do hereby declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which to it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or iigures of reference marked thereon, which form a part of this specification The present invention relates to that class of lubricators in which a measuring-cup is located between alubricant-receiverand passa ges leading to the valve-chests of a locomotive or other engine, said measuring-cup being so comzo bined with steam-ports that when it is properly shifted or set steam is admitted into the same for expelling its contents. A lubricator constructed upon the above-mentioned princi` ple forms the subject-matter of apatent granted to me on the 18th day of June, 1S7S,No. 201,874; and the object of the present invention is to provide such a construction and combination of devices whereby I am enabled to distribute the oil with greater ease and certainty than 3o heretofore and avoid the condensation of steam in the chamber containing the measuring-cup.

To these ends the invention consists essenl tially in the combination, with an oil-reservoir, of a hollow shell or cup, which is mounted on 3 5 a central horizontal a-Xis, and turns or rotates in contact with a vertical face-plate having a large port in communication with the oil-reservoir, and smaller ports in communication with a steam-inlet pipe and passages leading 4o to the valve-chests. The hollow shell or cup operates in a surrounding casing, and has two openings in its face, which serve for the admission and discharge of the oil and steam.

The invention also, consists in the construction and arrangementot parts, which will hereinaftcrl be more fully described, and then set forth in the claims.

In the drawings, Figure 1 is a vertical sectional view of a lubricator constructed according to the present invention. Fig. 2 is a front view, showing the face-plate with its various ports and passages, the measuring-cup and its surrounding casing being detached. Fig. 3 is a perspective view of the measurng-cup, constructed of a single piece or shell. Fig. 4 is a 55 rearv view ofthe base or casting, with its steaminlet and oil-discharge ports. Fig.5 isa modilied construction of the measuring or feed cup. Fig. 6 is a top view of the base or casting.

TheletterAdesignatesanoil-reservoir,whieh 6o may be ot' any approved construction, it being provided in the present instance with a transparent tube, a, i'or indicating the contents of the reservoir and observing'the discharge ot' oil therefrom. The base of the lubricator consists of a body or casting,`B, having a screwsocket at its top for the reception ofthe screwthreaded neck b of the oil-reservoir. The front of the casting or body B is turned smooth, so as to constitute a face-plate, C, which, as is 7o shown in Fig. 2, is of a circular shape. The periphery of the bodyB in rear ot' the faceplate C is screw-threaded, and a hollow shell or casing, D, is screwed thereto. This casing contains a hollow cup or cylindrical shell, E,

which has a circular front wall, c, corresponding in size and shape with the face-plate C. A stem, F,on the cup E projects through thefront end of the casing D, and is packed thereat by means of a nut, G, applied to a screw-threaded 8o neck, d, of the casing. A spring, U, serves to 'press the cup against the face-plate. A port or passage, H,extendingin a horizontal direc` tion through the top ot' the face-plate C, and communicating with the socketof the body B, into which the oil-reservoir is fitted, servesas as the conduitfor the oil from the reservior to the distributing-cup E. 0n each side of the port H, and below the same, are located smaller ports I J, which serve respectively for the dis- 9o charge of the oil from the cup E into the passagesv leading to the valve-chests and for the admission of live steam into the cup E for eX- pelling the contents thereof. The steam-ports J converge or run to an inlet chamber K 95 formed in the back of the body or casting B, and the mouth of this chamber is screwthreaded, and is designed for the reception ot' a steam-supply pipe connected with the boiler.

The oil-discharge ports I run horizontally roc through the face-plate C, and communicate with passages at the sides of the body B. Pipes- L, connected with these passages by screwcouplings or otherwise, extend to the valvechests ofa locomotive or other engine, and serve for conducting the lubricating material to the same. The front wall, e, of the cup E is provided with an opening, e2, for the admission and discharge ot' the oil, and with a smaller opening, c3, serving as an inlet for steam. The stem F of thc cup E, carries a handle or crank, F2, which serves for rotating or turning the cup in order to till the same with oil or discharge the latter into the distributing-pipes. A plate, M, attached to the periphery of the face-plate() by screws or otherwise, has an extension or arm, N, which extends over the periphery ofthe cup E and serves in conjunction with pins 0 on said cup to arrest or limit the movement thereof'. The cup, as shown in Figs.

l and 3, is cast ot one piece of metal; but I also contemplate making the same ot' two shells or sections,E-, joined together by a screw-connection, as is shown in Fig. 5. In this instance the peripheries of the shells are constructed with nuts or polygonal portions for facilitating the joining thereof.

The operation of a lubricator constructed in the above-described manner is follows, viz: Vhen the measuring-cup or feeder is in its normal position, which is preferably determined by the perpendicular setting of it-s handle, the large opening in the cup is brought opposite the top or large opening in the faceplate, andfhe small opening in the cup is closed by coming opposite the solid portion ot' the face-plate. When the parts are in this position oil is A freely admittedinto the measuringcup until it is full. In order to discharge its contents into the pipe leading to the valvechest at the right side of the locomotive, the handle is seized and the cup turned until one ofthe stop-pins thereon comes in contact with the arm on the face-plate, when the small opening in the cupis brought in line with the steamport and the larger opening over the oil-discharge port. The pressure of the live steam admitted into the cup will expel the oil therefrom and force it through the pipe leading to the valve-chest, it being obvious that the steam coming` direct from the boiler will be ot greater pressure or force than that present in the oil-delivery pipe, hence not preventing the proper feeding ofthe oil to the valve-chest. In order to supply oil to the valve-chest at the left side of the locomotive or engine, the cup is turned in a reverse direction from that above stated until the other stop-pin arrests the further movement of the cup. The openings in the latter are then brought opposite thesteam- -inlet port at the right side of the face-plate and the oil-discharge port atthe left side thereof, when the above-described admission of steam, resulting in the discharge of' the. oil, takes place.

I have in the construction of lubricator shown in the present instance had special reference to the lubrication of the valve-chests of alocomotive-engine by one and the same device. I desire it to be understood, however, that I propose making such changes or modifications, without departing from the spirit of my invention, as will adapt the device for use in connection with a single valve-chest or other partofan engine. For example, the shaft or axis of thc measuring-cup is made to pass through the body or casting having the oil and steam ports, and, as will be obvious in a single-acting lubricator, I require only three openings in the face-plate-one at the top for the admission of the oil and two openings arranged in a diagonal line for the admission of the steam into the cup and discharge of the oil therefrom.

Having thus described my invention, whatI claim as new, and desire to secure by Letters Patent, is-

1. In a lubricator, the combination of a hollow rotating cup having openings in its vertical front wall and mounted on a horizontal axis, a casing or shell surrounding said cup, and a body or casting having a vertical faceplate provided with openings for the admission of oil and steam and an opening for the discharge of oil and steam, with a lubricant-receiver, and devices, substantially as shown, for turning the measuringcup, as herein set forth.

2. In a lubricator, the combination of the body or casting having a vertical face-plate, top oil-inlet opening, steam-chamber, passages diverging from the latter, and oil-discharge openings, with the rotating measuring-cup, its surrounding casing, and a lubricant-receiver, substantially as herein set forth.

3. Theverticalface-platehavingastop-plate, and the measuring-cup having pins, in combination with the body or base, lubricant-receiver, and casing surroundingthe measuringcup, as herein set forth.

In testimony whereofI atix my signature in presence ot' two Witnesses.

HIRAM ALLTON.
